Visco Safety Fuse
A slow-burning safety fuse made from visco powder encased in a flexible textile or plastic sheath, designed for reliable ignition delay in blasting operations. It falls under HTS 3603.10.00.00 as a safety fuse used to initiate detonators in mining and construction explosives. The fuse burns at a consistent rate, typically 1 foot per 30-40 seconds, ensuring safe standoff distances.
Cotton-Core Safety Fuse
Traditional black powder safety fuse with a cotton core impregnated with gunpowder, wrapped in multiple textile layers for waterproofing and durability. Classified under HTS 3603.10.00.00 for its role as a low-explosive time-delay fuse in demolition and quarrying. Burn speed is approximately 35-45 seconds per meter.
Shock Tube Safety Fuse
A non-explosive plastic tube filled with reactive powder that transmits a low-energy shock wave to initiate detonators remotely. Though technically a signal tube, it's used interchangeably with safety fuses in mining under HTS 3603.10.00.00. Provides minimum run-up distance with high reliability.
Instantaneous Safety Fuse
High-speed safety fuse variant burning at over 100 m/s for rapid sequential blasting in tunnel construction. Made with reinforced gunpowder core and polymer coating for moisture resistance. HTS 3603.10.00.00 covers this as a specialized safety fuse for industrial detonations.
